Solution Overview
Problem
Conventional machines for processing containers lack flexibility, requiring elaborate setup processes and extended times to produce different container types, filling materials, and product variations, leading to higher production costs and inflexibility to meet customer demands.
Innovation Solution
A machine with multiple heating stations, reshaping stations, and decorating/filling devices that allow for individual processing and assignment of specific tasks, enabling the production of various container types, decorations, and fillings without extensive reconfiguration, utilizing a control system to manage the assignment of heating, reshaping, decorating, and filling processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional machines use fixed rigid functions and processes, then machine structure is simple and reliable, but flexibility and adaptability to different container types and products are poor
Solution Approach 1:
The machine is divided into multiple independent processing stations (heating station, reshaping station, decorating station, filling station), each capable of being individually configured and assigned to different tasks. This segmentation allows flexible reconfiguration for different container types without redesigning the entire machine.
Solution Approach 2:
Each processing station is designed with universal capabilities to handle multiple container types and product variations. The stations can be dynamically assigned to different functions through the control device, enabling one machine to perform multiple roles for different production requirements.
2Productivity
If conventional machines are configured for single container type production, then production process is simple and stable, but setup time and costs for changing to different container types are high
Solution Approach 1:
The machine employs dynamic assignment of processing stations through a control device that can reallocate stations to different container types and products on demand. This dynamic reconfiguration eliminates lengthy manual setup processes while maintaining stable production once assigned.
Solution Approach 2:
Multiple processing stations are pre-configured with different capabilities and ready for immediate assignment. The control device can quickly switch between pre-prepared station configurations, avoiding time-consuming setup procedures when changing production types.
3Adaptability or versatility
If conventional machines produce only one product type, then production process is optimized and efficient, but ability to produce multiple product variants simultaneously is limited
Solution Approach 1:
The control device creates virtual copies of production configurations for different product variants. Each processing station can be assigned to produce a specific variant, and the control system manages multiple virtual production lines simultaneously, enabling diverse product output without proportional increase in physical complexity.
